In order to lock on to targets with the seeker missile in Metroid Prime 3: Corruption, I have to press and hold the down button on the D-Pad. However doing so fires a single missile, which is wasted. With only ~100 missiles this can be a big waste! Is theer a way to charge up the seeker missiles and lock on to targets without wasting this first missile?
If you fire a regular beam charge shot and then immediately hold down the missile button, you should be able to start charging the seeker missile without having to "waste" a shot.
The key is to begin holding down the missile button during the "cooldown" period of the charge shot animation (when you are unable to fire anything, beam or missile).
